To all 'whom z' t may concern):

Beit known that we, EMERSON F. Cora:

and ARTHbRLJ CON AD, citizens of the Unitedj'Stat'es', residing'at Frankfort, in the 'county-of Olinton and State of Indiana,

have inv'ented certain "new and useful Improvements in Resilient Wheels; and 'we do *herebydeclarethe following-to be a full,

' clear, and exact description of the invention,

such-as willenable others skilled in the art to which it appertainsto make anduse the isame.

' This invention relates to improvements resilient orf spring wheels and has for an "obj ect' to improve the construction of spring '1 wheels so as to provide a resilient spring "wheel which will supplant the pneumatic tire Wheelnow in use and at the same time ive the 'samecushioning and-resilient elfect a 's does such pneumatic wheels; I r j further object of this invention isthe provision of a spring wheel which will-give the same'cushioning and resilient action as j does a pneumatic Wheel when the same encounters'rough or uneven road beds A further object of iIlYBIlillOIiiS to provide a resilient wheel of thisoharacter which will be a simple, practi caland comparatlvely inex penslve 4 structure, andone that can be manufactured and assembledfat away showing our improved wheel asmadei in accordance with this invention,

Referring more particularly to the drawings, ldesignates the hub of the wheel, 2 the spokes thereof, and 3 the telly. r

In applying our improved structure, we first secure a steel inner rim 4 to the felly which inner rim is arranged circumferen- BE IL' N f T i specification P e.
